Characteristics of the array spectrometer ST2222

1. Silicon photodiode array (22 double-row) sensors

    The larger array sensor, the stronger light will not be saturated, the lower light sensitivity is higher and the wider spectrum response range, has guaranteed the instrument measurement speed, the accuracy, the stability and the consistency, grasps the core technology, with the same platform of international standards, achieve perfect compatibility.

2、Adopt full waveband balanced LED light source

    The array spectrometer ST2222 adopts 400 ~ 700nm full waveband balanced LED and UV light source as the illumination light source, which has enough spectrum distribution in the visible light range and avoids the loss of the spectrum of white LED in the specific wave band,Fluorescent materials can also be easily measured.

3、Grating splitting technology

    The use of plane grating spectroscopy technology, with a higher resolution, so that more accurate color measurement.

4、Intelligent base, automatic calibration

     It is equipped with intelligent calibration base, can carry out automatic white board calibration, professional grade standard white board reflectivity R% ≥95% , good surface uniformity, high stability, can obtain repeated accurate data.

5、New fashion appearance design based on ergonomics

    The hand-held position and the position of the measuring button are carefully designed to meet different holding habits, smooth and fine surface, derived from the professional appearance treatment technology.

6、 Equipped with five measuring calibers larger to meet the sample measurement needs

    The array spectrometer ST2222 is equipped with Φ8mm/φ10mm platform, Φ4mm/φ5mm platform

    Φ8mm/φ10mm sharp tip, Φ4mm/φ5mm sharp tip and 1x3mm calibre, which meet the measurement requirements of most special samples.

7、Camera positioning can clearly observe the area to be measured

     The ST2222 array spectrophotometer has a built-in camera, which can accurately judge whether the object is the target center, and improve the measuring efficiency and accuracy.

    8、Excellent interstation and repeatability

    The repeatability ΔE * ab ≤0.018, the Inter-instrument Error ΔE * AB ≤0.18 data is stable and reliable, which ensures the consistency of the data measured by multiple devices, and can be used for color matching and accurate color transfer.

9、Multi-color measurement space and observation light source

    Provide CIE LAB, XYZ, Yxy, LCH, Cie Luv, s-RGB, HunterLab, βxy, DIN Lab99 Munsell (C/2) color space, and a variety of observation light sources

    A, B, C, D50, D55, D65, D75, F 1, f 2, F 3, F 4, F 5, F 6, F 7, F 8, F 9, F10, F11, F12, CWF, U30, U35, DLF, NBF, TL83, TL84, ID50, ID65, LED-B1, LED-B2, LED-B3, LED-B4, LED-B5, LED-B6, LED-BH1, LED-RGB1, LED-V1, LED-V2, LED-V3, customizable light source, it can meet the special measuring requirements under different measuring conditions.

10、Adopt D/8sci/SCE synthesis technology

    The measurement structure of D/8(SCI/SCE) is adopted to reflect the color itself more objectively and reduce the influence of the surface texture of the object on the test results, which conforms to the standard CIE No. 15, GB/T 3978, GB 2893, GB/t 18833, ISO7724-1, ASTM E1164, DIN 5033 TEIL7

11、Double light path system is more stable in color measurement

    Double optical path system, when the environment changes, to ensure that the measurement data more stable and accurate.  

12、Support Android, IOS, Windows, wechat small programs, HUAWEI Harmony OS

    The array spectrometer ST2222 is equipped with SQCX software, which is suitable for quality monitoring and color data management in various industries. The user's color management data, compare color differences, generate test reports, provide a variety of color space measurement data, customized customer color management.
